Hi all Audi Kruse I have a problem and that despite the engine ( 2.3l 5 cylinder NG) is warm and it does not have a temperature! Because Thermostatt I changed at the beginning of this year I always stay loud water indicator and stand on quarter about 70-80 degrees in the city he goes on 90 think that’s ok! What else can it be that the heating only brings lukewarm air???
